DVP-ES2/EX2/SS2/SA2/SX2/SE Operation Manual - Programming

¾ When C251 counts up and the value in C251 varies from 100 to101, DHSCS instruction

¾ When C251 counts down and the value in C251 varies from 100 to 99, DHSCR

instruction resets M0.

¾ Timing diagram for the comparison:

Program Example 3:

Executes interrupt subroutine by applying software comparator.

¾ When value in C235 varies from 99 to100, interrupt subroutine triggered by I010 executes

immediately to set Y0 ON.

Points to note:

¾ If operand D is specified as S, M or Y0~Y3 for the above high speed comparison, the compare

result will immediately output to the external points Y0~Y3 (Y0~Y5 for SS2/SX2). However, if

D is specified as Y4~Y337, external outputs will be updated till the end of program (delay for

one scan cycle).
